compile significant portions of the tree at -O1 instead of -O2, and sometimes -Os/-O0 is required, and others none works. i'd guess that some instructions in the .md file are generating more assembler than they claim to be since all these errors are due too large offsets. but fixing that is work for someone else, or at least another day :-)

/* If this file is compiled with threads support, it must
|
|
#define __GTHREADS 1
|
|
to indicate that threads support is present. Also it has define
|
|
function
|
|
int __gthread_active_p ()
|
|
that returns 1 if thread system is active, 0 if not.
|
|
|
|
The threads interface must define the following types:
|
|
__gthread_key_t
|
|
__gthread_once_t
|
|
__gthread_mutex_t
|
|
__gthread_recursive_mutex_t
|
|
|
|
The threads interface must define the following macros:
|
|
|
|
__GTHREAD_ONCE_INIT
|
|
to initialize __gthread_once_t
|
|
__GTHREAD_MUTEX_INIT
|
|
to initialize __gthread_mutex_t to get a fast
|
|
non-recursive mutex.
|
|
__GTHREAD_MUTEX_INIT_FUNCTION
|
|
some systems can't initialize a mutex without a
|
|
function call. On such systems, define this to a
|
|
function which looks like this:
|
|
void __GTHREAD_MUTEX_INIT_FUNCTION (__gthread_mutex_t *)
|
|
Don't define __GTHREAD_MUTEX_INIT in this case
|
|
__GTHREAD_RECURSIVE_MUTEX_INIT
|
|
__GTHREAD_RECURSIVE_MUTEX_INIT_FUNCTION
|
|
as above, but for a recursive mutex.
|
|
|
|
The threads interface must define the following static functions:
|
|
|
|
int __gthread_once (__gthread_once_t *once, void (*func) ())
|
|
|
|
int __gthread_key_create (__gthread_key_t *keyp, void (*dtor) (void *))
|
|
int __gthread_key_delete (__gthread_key_t key)
|
|
|
|
void *__gthread_getspecific (__gthread_key_t key)
|
|
int __gthread_setspecific (__gthread_key_t key, const void *ptr)
|
|
|
|
int __gthread_mutex_lock (__gthread_mutex_t *mutex);
|
|
int __gthread_mutex_trylock (__gthread_mutex_t *mutex);
|
|
int __gthread_mutex_unlock (__gthread_mutex_t *mutex);
|
|
|
|
int __gthread_recursive_mutex_lock (__gthread_recursive_mutex_t *mutex);
|
|
int __gthread_recursive_mutex_trylock (__gthread_recursive_mutex_t *mutex);
|
|
int __gthread_recursive_mutex_unlock (__gthread_recursive_mutex_t *mutex);
|
|
|
|
All functions returning int should return zero on success or the error
|
|
number. If the operation is not supported, -1 is returned.
|
|
|
|
Currently supported threads packages are
|
|
TPF threads with -D__tpf__
|
|
POSIX/Unix98 threads with -D_PTHREADS
|
|
POSIX/Unix95 threads with -D_PTHREADS95
|
|
DCE threads with -D_DCE_THREADS
|
|
Solaris/UI threads with -D_SOLARIS_THREADS
